Submersible sewage pump is an important water pump in the sewage treatment industry, using pump and motor Siamese design, you can dive into the liquid work. So what are the advantages and disadvantages of this pump working in special circumstances? What should we pay attention to when using? Advantages and Disadvantages of Submersible Sewage Pumps and Precautions Introduction Advantages of Submersible Sewage Pump 1. Compact structure and small floor space. Submersible sewage pump submersible work, so can be installed directly in the sewage tank, without the need to build a dedicated pump room for the installation of pumps and machines, you can save a lot of land and infrastructure costs. 2, easy installation and maintenance. Small sewage pump can be freely installed, large sewage pumps are generally equipped with automatic coupling device can be automatically installed, installation and maintenance quite convenient. 3, continuous operation for a long time. Sewage pump due to pump and motor coaxial, short shafts, rotating parts light weight, so the bearing load (radial) is relatively small, life expectancy much longer than the average pump. 4, there is no cavitation damage and irrigation water and other issues. Especially after the point to the operator has brought great convenience. Submersible sewage pump shortcomings The most critical issue for the submersible sewage pump is the reliability of the problem, because the sewage pump is used in the occasion of the liquid; the medium is transported with a mixed liquid containing solid materials; pump and the motor close to; Pump vertical layout, the weight of rotating parts and impeller water pressure in the same direction. These problems make the sewage pump in sealing, motor carrying capacity, bearing arrangement and selection requirements than the average sewage pump is higher. Submersible sewage pump Notes 1, when the humidity sensor or temperature sensor alarm, or when the pump vibration, noise, abnormal; or output water pressure drops, the power consumption increased significantly, it should immediately shut down the submersible sewage pump Overhaul 2, some poorly sealed submersible pump immersed in water for a long time, even if not used, the insulation value will gradually decline, eventually unable to vote, and even than the continuous operation of the submersible sewage pump in the water short working time Insulation disappeared. So the submersible pump in the suction tank sometimes can not play a backup role, if conditions permit, can be dry standby outside the pool, and so on in the operation of a submersible pump in the event of failure, immediately stop up after the backup pump and then down go with. 3, submersible pump can not be too often open, stop, otherwise it will affect the submersible pump life. When the submersible pump is stopped, the water in the pipeline will generate backflow, immediately restarting it will cause the load of the pump to start overloading and bear the unnecessary impact load. In addition, if the submersible pump is too frequently open and stopped, the pump will be damaged Less capable parts, and bring the entire pump damage. 4, stop, can not restart the motor completely stopped before operation. 5, check the pump must be cut off the power. 6, submersible pump work, do not wash goods in the vicinity, swimming or put livestock into the water, so as to avoid electric shock when the electric shock occurred.
